Fixed Film Reactors (FFR), also known as attached biofilm reactors, supports the growth of beneficial microorganisms to break down pollutants. Wastewater is sprayed onto the media to grow the desired bacteria that consume pollutants.
High Treatment Efficiency
Biofilm grows on media surfaces, providing a large active area for pollutant degradation
Compact Design
Requires less space compared to traditional suspended-growth systems like activated sludge
Stable Operation
Biofilm protects microbes from shocks and fluctations in flow or load
Effective Nutrient Removal
Supports nitrification and denitrification processes for nitrogen control
Low Sludge Production
Produces less excess sludge, reducing handling and disposal costs
Adaptable to Various Wastewater Types
Suitable for municipal, industrial, and decentralized treatment
Energy Efficient
Often requires less aeration and lower operational costs than conventional systems
Fixed Film Reactors offer exceptional versatility, ideal for treating both domestic and industrial wastewater. They can operate efficiently under aerobic, anoxic, or anaerobic conditions, making them adaptable to a wide range of treatment needs. With lower energy consumption compared to other technologies, they also provide a more sustainable, cost-effective solution for long-term performance.
Applied for treating high-strength or variable load wastewater.
Used in small to mid-sized treatment plants for stable BOD and ammonia removal, especially where space or operator resources are limited.
Provides consistent, compact treatment for facilities with fluctuating occupancy and limited infrastructure.
Handles organic-rich effluents from seasonal operations with minimal operator oversight.
Nviro’s fixed film reactors are designed for stable, low-maintenance biological treatment in demanding conditions. Our systems use high-surface-area media to support dense biofilm growth, ensuring consistent performance even with variable loading or flow rates. Engineered in-house and built for duability, Nviro’s solutions are ideal for decentralized, industrial, and reuse applications, delivering reliable BOD and ammonia removal with simplified operation, minimal sludge production, and a compact footprint.
